I am still trying to figure my flocks sexs out too. My leghorns were easy to tell my others not so much lol
Most of us are confused at some time or other .I'd be looking for eggs . This is a good time of year to have them start laying . You should have eggs most of the winter. I have 30 week old pullets that have gone broody already 
. Hopefully yours won't because it's late in the season. It looks like you've done a good job so far.

If your avatar is your flock I don't see any cockerels. But post some pictures and we can help. When you post the picture from the upload it gives you two options. When that comes up and you see the picture click on full image , only on full image .If you click on the picture it loads as an attachment .
